Wave demonstrator
Apparatus for demonstrating standing waves on a string (Melde's experiment) with a vibration block and a set of weights.
Mechanical vibration and wave demonstration apparatus consisting of 7 components: horizontal beam, demonstration string, vibration unit with function generator, triangular support, weight set and information panel. Designed for 6 demonstrations: the formation of standing waves on a stretched string, nodes and antinodes of transverse waves, the dependence of the number of antinodes on the string tension and the frequency of the vibrator, the condition for the formation of a standing wave and the study of wave speed.

- 2.Demo thread - 1 pc.
- 3.Hook for hanging a mass - 1 pc.
- 4.Triangular support - 1 pc.
- 5.Vibration block (function generator) - 1 pc.
- 6.Set of weights - 1 set.
- 7.Information support panel - 1 pc.
- Formation of standing waves on a stretched thread (Melde's experiment)
- Transverse waves on a thread: crests, troughs, wavelength, nodes and antinodes
- Dependence of the number of antinodes of a standing wave on the tension force of the thread (mass of the suspended load)
- Dependence of the number of antinodes of a standing wave on the vibration frequency of the vibrator
- Condition for the formation of a standing wave: the length of the thread is equal to an integer number of half-waves
- Study of the dependence of the transverse wave speed on the tension and linear density of the thread
